FIRE-EXTINGUISHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 684,072, dated October8, 1901.

Application filed May 25,1901. Serial No. 61,839. (No model.)

To @ZZ whom t may concern:

Be it known that I, ALEXANDER LOGAN, a British subject, and a residentof North Sydney, in the county of Cape Breton, and Province of NovaScotia, Dominion of Canada, have invented a new and ImprovedFire-Extinguishing Apparatus, of which the following is a full, clear,and exact description.

This invention relates to improvements in apparatus for extinguishingvfires in buildings; and the object is to provide in connection with abuilding a system of perforated pipes having valves adapted to be openedby weights or other pressure when released by the burning away ofsupporting cords or cables.

I will describe a fireextinguishing apparatus embodying my invention andthen point out the novel features in the appended claims.'

Reference is to be had to the accompanying drawing, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in the gure, which is a sectional elevation of abuilding, showing my invention as applied thereto.

Referring to the drawing, 1 designates a building, and extended upwardat one end of the building is a water-pipe 2, having connection with amainr3. This pipe 2 has a section 4 extended along the top of the roof,and this section 4 is provided with perforations through which water maypass to the roof, and at the ends of the building are branch pipes 5,which are also perforated.

In a horizontal section 6 of the pipe 2, which is arranged in theground, is a valve 7, from which an operating-rod 8 extends upward andhas a bearing at its upper end in a bracket 9, attached to the building,and on this upper end is a crank 10, from which a chain 11 passes over apulley 12 and has connected to its end a weight 13. From the weight 13 arope 14 extends upward and passes back and K forth along the roof, asclearly indicated in the drawing. This rope 14 passes over a series ofpulleys cn the roof and has its end secured to the roof. Ropes 15 and 1Gconnect with the rope 14, passing, respectively, over pulleys 17 and 18,and connect at their ends with supports secured to the eaves or to thelower edges of the roof. These supports are in the form of boards 15a16, mounted to swing at the edge of the roof and designed when movedinward in case of fire to direct water to the sides of the building asit passes off the roof.

A-main supply-pipe 19 extends through the several upper rooms of thehouse, and arranged in this pipe 19, within the building, is a valve 20.Also extended through the up per rooms of the building is a rope 21whichextends through an opening in the end of the building and over a pulley22 and is connectedto a weight 23. From this weight 23 a chain 24extends to an arm 25, attached to the stem of a valve 26, arranged inthe pipe 2 above its connect-ion with the pipe 19. This arm 25 isprovided at its end with a cuttingblade 26a for a purpose to behereinafter described. The rope 21 passesthrough opena ings in theseveral partitions of the upper rooms of the building, and thence over apulley 27 and downward to a connection with a hook 28 at the lowerportion of the wall of a shaft or hallway 29.

In the upper room 30 a perforated pipe 3l leads downward from the pipe19, and connected to a valve in this pipe 31 is an arm 32, connected bya rope 33 with a weight 34. The said rope passes over a pulley 35 andextends along the ceiling of the room. In the room 36 a perforated pipe37 extends downward from the pipe 19, and in this pipe 37 is a valve,the stem of which is connected to an arm 38, and suspended in the roomby means of a rope 39 is a weight 40. As in the rst instance, this rope39 extends along the ceiling of the room. In the room 41 the pipe 19 isprovided with a valve, on the stem of which is an arm 42, connected by'a rope or cord with a weight 43.

Within the shaft or hallway 29 perforated pipes 44 lead downward fromthe pipe 19, andalso communicating with said pipe 19 and extended acrossthe upper portion of the shaft or hallway is a perforated pipe 45.

In the lower rooms 46 and 47 are perforated pipes 48 and 49, which areprovided with valves and connect with a pipe 50, leading from the main3. Extended through the rooms 46 and 47 and into the room 51 is a rope52, which at its end within the room 51 passes over a pulley 53 andconnects with a weight 54, and this weight has a connection with thehammer 55 of a bell 56. A rope 57 IOO extends through the room 47 andinto the room 5l over a pulley 58 to a connection with a weight 59, andthis weight has a connection with the hammer 55.

In operation ythe valve 7 will be normally closed and the valve 26normally open. Should a tire occur on the roof, the rope 14 will beburned away, permitting the weight 13 to fall, which will rotate the rodS, openingsaid valve 7, so that water may pass from the main pipethrough the pipe 2 and through the sections 4 and 5, from which it willpass through the perforations. Should a fire occur Within the house orin the upper rooms thereof or the hallway, the rope 2l will be burnedaway, permitting the weight 23 to fall, which will close the valve 2G,and during the closing of this valve the cutter 26 will sever the rope14C, permitting the weight 13 to fall, and thus open the valve 7, asbefore described. It the fire is confined to one of the roomssay theroom SO-the rope 33 will be burned away, permitting the weight 34 toopen the valve in the pipe 21, thus allowing the escape of water throughthe perforat-ions in said pipe, and this same operation will take placein any one of the upper rooms or hallway. It is to be understood thatthe same system may be employed in the lower rooms.

In the alarm device should the rope 52 be burned away the weight 54 willfall, causing the hammer 55 to strike the bell 56. The same result willbe obtained should the rope 57 be burned away.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. ln a fire-extinguishing apparatus, a pipe leadingfrom a main and having a perforated portion extended along the roof of abuilding, a valve in said pipe, a rod extended from the valve, a weighthaving connection with said rod, a rope or the like extended along theroot' of the building and normally holding said Weight suspended,swinging boards at the edge of the roof, and connections between saidboards and the rope, substantially as specified.

2. In a tire-extinguishing apparatus, a pipe leading from a main andhaving a perforated portion extending along the root` of a building, aValve in said pipe, a rod extended from the valve, a weight havingconnection with said rod, a rope extended in a plurality of stretchesalong the roof of the building and normally holding said weightsuspended, rollers on the roof over which said rope passes, swingingboards at the edges of the roof, and connections between said boards andsaid rope, substantially as specified.

3. In a fire-extinguishing apparatus, a pipe leading from a water-main,a valve in said pipe, a weight for opening said valve, a fusible supportfor said weight, a pipe leading through the building and extended fromthe first-named pipe, perforated pipes extended from said pipe withinthe building, valves in the perforated pipes, weights for opening saidvalves, ropes for suspending said weights, a rope extended through thebuilding, a weight at the outer end of said rope, a valve in thetiret-named pipe above its connection with the pipe extended through thebuilding, an arm on the stein of said valve having a cutter, and aconnection between said weight and said arm, substantially as specified.

-In testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.

ALEXANDER LOGAN.
